1. CHECK DLC3

(a) The vehicle's combination meter (CPU) uses CAN and ISO 9142-2 for communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches ISO 9142-2 format.





HINT
If the display shows an error message after having connected the cable of the Techstream to the DLC3, engine switch on (IG), and operated the tester, there is a problem on either the vehicle side or the tool side.

If communication is normal when the tool is connected to another vehicle, inspect the DLC3 on the original vehicle.

If communication is still impossible when the tool is connected to another vehicle, the problem is probably in the tool itself. Consult the Service Department listed in the tool's instruction manual.
